Acer Predator XB273K GP Monitor Flashing Issue in HDR & High Brightness Modes

Hi all,

I have been experiencing a black screen flashing issue with my Acer Predator XB273K GP 27" 4K monitor. It started a few weeks ago when it would have black flashes when I first started my PC, however, it will only last for a few minutes and then stop flashing. Over time, the flashes started lasting longer before going away, and today, it did not stop at all (it has been more than 2 hours).

What I’ve Tried:

  • Tested multiple cables (DisplayPort & HDMI)
  • Updated all drivers and software
  • Factory reset the monitor & checked for firmware updates
  • Tested with and without G-Sync, refresh rates and HDR
  • Verified issue persists even with no input (No Signal Screen)

What I Have Found:

The only way I could stop the flashing was by switching the monitor from HDR Mode to Eco Mode. All other modes, such as Action, Racing, and Graphics, also exhibited the same flashing issue. I tried to understand the difference between Eco Mode and the other modes and discovered that brightness was the cause of the problem. Even when I stay in Eco Mode, increasing the brightness from 44 to 100 causes the flashing to resume. I've noticed that the higher the brightness, the faster the flashing occurs, while lower brightness levels result in longer intervals between flashes.

I’ve recorded the issue in HDR mode, Eco Mode, and with brightness adjustments.

Does anyone know what might cause this? Is it a hardware issue, or are there fixes I haven’t tried? Any help is much appreciated!
